This application claims the benefit of priority of U.S. Provisional Application No. 63/088,759, filed Oct. 7, 2020, the contents of which are incorporated by reference herein in its entirety.

The disclosure relates to modulators of Cystic Fibrosis Transmembrane Conductance Regulator (CFTR), pharmaceutical compositions containing the modulators, methods of treatment of cystic fibrosis using such modulators and pharmaceutical compositions, combination therapies and combination pharmaceutical compositions employing such modulators, and processes and intermediates used for making such modulators.

Cystic fibrosis (CF) is a recessive genetic disease that affects approximately 70,000 children and adults worldwide. Despite progress in the treatment of CF, there is no cure.

In patients with CF, mutations in CFTR endogenously expressed in respiratory epithelia lead to reduced apical anion secretion causing an imbalance in ion and fluid transport. The resulting decrease in anion transport contributes to increased mucus accumulation in the lung and accompanying microbial infections that ultimately cause death in CF patients. In addition to respiratory disease, CF patients typically suffer from gastrointestinal problems and pancreatic insufficiency that, if left untreated, result in death. In addition, the majority of males with cystic fibrosis are infertile, and fertility is reduced among females with cystic fibrosis.

Sequence analysis of the CFTR gene has revealed a variety of disease causing mutations (Cutting, G. R. et al. (1990) Nature 346:366-369; Dean, M. et al. (1990) Cell 61:863:870; and Kerem, B-S. et al. (1989) Science 245:1073-1080; Kerem, B-S et al. (1990) Proc. Natl. Acad. Sci. USA 87:8447-8451). To date, greater than 2000 mutations in the CF gene have been identified; currently, the CFTR2 database contains information on only 432 of these identified mutations, with sufficient evidence to define 352 mutations as disease causing. The most prevalent disease-causing mutation is a deletion of phenylalanine at position 508 of the CFTR amino acid sequence and is commonly referred to as the F508del mutation. This mutation occurs in many of the cases of cystic fibrosis and is associated with severe disease.

The deletion of residue 508 in CFTR prevents the nascent protein from folding correctly. This results in the inability of the mutant protein to exit the endoplasmic reticulum (ER) and traffic to the plasma membrane. As a result, the number of CFTR channels for anion transport present in the membrane is far less than observed in cells expressing wild-type CFTR, i.e., CFTR having no mutations. In addition to impaired trafficking, the mutation results in defective channel gating. Together, the reduced number of channels in the membrane and the defective gating lead to reduced anion and fluid transport across epithelia. (Quinton, P. M. (1990), FASEB J. 4: 2709-2727). The channels that are defective because of the F508del mutation are still functional, albeit less functional than wild-type CFTR channels. (Dalemans et al. (1991), Nature Lond. 354: 526-528; Pasyk and Foskett (1995), J. Cell. Biochem. 270: 12347-50). In addition to F508del, other disease-causing mutations in CFTR that result in defective trafficking, synthesis, and/or channel gating could be up- or down-regulated to alter anion secretion and modify disease progression and/or severity.

CFTR is a cAMP/ATP-mediated anion channel that is expressed in a variety of cell types, including absorptive and secretory epithelia cells, where it regulates anion flux across the membrane, as well as the activity of other ion channels and proteins. In epithelial cells, normal functioning of CFTR is critical for the maintenance of electrolyte transport throughout the body, including respiratory and digestive tissue. CFTR is composed of 1480 amino acids that encode a protein which is made up of a tandem repeat of transmembrane domains, each containing six transmembrane helices and a nucleotide binding domain. The two transmembrane domains are linked by a large, polar, regulatory (R)-domain with multiple phosphorylation sites that regulate channel activity and cellular trafficking.

Chloride transport takes place by the coordinated activity of ENaC and CFTR present on the apical membrane and the Na⁺—K⁺-ATPase pump and Cl⁻ channels expressed on the basolateral surface of the cell. Secondary active transport of chloride from the luminal side leads to the accumulation of intracellular chloride, which can then passively leave the cell via Cl⁻ channels, resulting in a vectorial transport. Arrangement of Na⁺/2Cl⁻/K⁺ co-transporter, Na⁺—K⁺-ATPase pump and the basolateral membrane K⁺ channels on the basolateral surface and CFTR on the luminal side coordinate the secretion of chloride via CFTR on the luminal side. Because water is probably never actively transported itself, its flow across epithelia depends on tiny transepithelial osmotic gradients generated by the bulk flow of sodium and chloride.

A number of CFTR modulating compounds have recently been identified. However, compounds that can treat or reduce the severity of cystic fibrosis and other CFTR mediated diseases, and particularly the more severe forms of these diseases, are still needed.

Methods of Treatment

Any of the novel compounds disclosed herein, such as for example, compounds of Formula I, compounds of any one of Formulae Ia, IIa, IIb, III, IV, V, VIa, and VIb, Compounds 1 to 369, tautomers thereof, deuterated derivatives of those compounds and tautomers, and pharmaceutically acceptable salts of any of the foregoing, can act as a CFTR modulator, i.e., it modulates CFTR activity in the body. Individuals suffering from a mutation in the gene encoding CFTR may benefit from receiving a CFTR modulator. A CFTR mutation may affect the CFTR quantity, i.e., the number of CFTR channels at the cell surface, or it may impact CFTR function, i.e., the functional ability of each channel to open and transport ions. Mutations affecting CFTR quantity include mutations that cause defective synthesis (Class I defect), mutations that cause defective processing and trafficking (Class II defect), mutations that cause reduced synthesis of CFTR (Class V defect), and mutations that reduce the surface stability of CFTR (Class VI defect). Mutations that affect CFTR function include mutations that cause defective gating (Class III defect) and mutations that cause defective conductance (Class IV defect). Some CFTR mutations exhibit characteristics of multiple classes. Certain mutations in the CFTR gene result in cystic fibrosis.

In some embodiments, the disclosure also is directed to methods of treatment using isotope-labelled compounds of the afore-mentioned compounds, or pharmaceutically acceptable salts thereof, wherein the formula and variables of such compounds and salts are each and independently as described above or any other embodiments described above, provided that one or more atoms therein have been replaced by an atom or atoms having an atomic mass or mass number which differs from the atomic mass or mass number of the atom which usually occurs naturally (isotope labelled). Examples of isotopes which are commercially available and suitable for the disclosure include isotopes of hydrogen, carbon, nitrogen, oxygen, phosphorus, fluorine and chlorine, for example ²H, ³H, ¹³C, ¹⁴C, ¹⁵N, ¹⁸O, ¹⁷O, ³¹P, ³²P ³⁵S, ¹⁸F and ³⁶Cl, respectively.

The isotope-labelled compounds and salts can be used in a number of beneficial ways. They can be suitable for medicaments and/or various types of assays, such as substrate tissue distribution assays. For example, tritium (³H)- and/or carbon-14 (¹⁴C)-labelled compounds are particularly useful for various types of assays, such as substrate tissue distribution assays, due to relatively simple preparation and excellent detectability. For example, deuterium (²H)-labelled ones are therapeutically useful with potential therapeutic advantages over the non-²H-labelled compounds. In general, deuterium (²H)-labelled compounds and salts can have higher metabolic stability as compared to those that are not isotope-labelled owing to the kinetic isotope effect described below. Higher metabolic stability translates directly into an increased in vivo half-life or lower dosages, which could be desired. The isotope-labelled compounds and salts can usually be prepared by carrying out the procedures disclosed in the synthesis schemes and the related description, in the example part and in the preparation part in the present text, replacing a non-isotope-labelled reactant by a readily available isotope-labelled reactant.

In some embodiments, the isotope-labelled compounds and salts are deuterium (²H)-labelled ones. In some specific embodiments, the isotope-labelled compounds and salts are deuterium (²H)-labelled, wherein one or more hydrogen atoms therein have been replaced by deuterium. In chemical structures, deuterium is represented as “D.”

Example 50: Preparation of Compound 156 Step 1: tert-Butyl 2-[[(1R)-4,4,4-trifluoro-1-(hydroxymethyl)-3,3-dimethyl-butyl]amino]-7-azaspiro[3.5]nonane-7-carboxylate

In a 250 mL flask, (2R)-2-amino-5,5,5-trifluoro-4,4-dimethyl-pentan-1-ol (hydrochloride salt) (1.513 g, 6.826 mmol) was added to a solution of tert-butyl 2-oxo-7-azaspiro[3.5]nonane-7-carboxylate (1.496 g, 6.251 mmol) in anhydrous DCE (10 mL) under nitrogen and stirred at rt for 20 minutes (cloudy solution). sodium triacetoxyborohydride (3.98 g, 18.78 mmol) was divided into 3 separate portions and added to give a thick suspension (magnetic stirring still efficient). The mixture was stirred at rt for 22 hours. The mixture was cooled in an ice bath (internal temp=2° C.), then HCl (10 mL of 4 M, 40.00 mmol) was added very slowly, keeping the temperature between 2° C. and 6° C. A solution of potassium carbonate (10 g, 72.36 mmol) in water (10 mL) was added, while keeping the temperature below 10° C., then another portion of water (15 mL) (final pH=11) was added, followed by DCM (20 mL). The two phases were separated. The aqueous phase was further extracted with DCM (30 mL). The combined extracts were washed with saturated sodium bicarbonate (30 mL), dried over sodium sulfate and the solvents were evaporated. Drying under vacuum gave crude tert-butyl 2-[[(1R)-4,4,4-trifluoro-1-(hydroxymethyl)-3,3-dimethyl-butyl]amino]-7-azaspiro[3.5]nonane-7-carboxylate (2.446 g, 96%) as a brown honey-like resin.

Step 2: 3-[[4-[(2R)-2-[(7-tert-Butoxycarbonyl-7-azaspiro[3.5]nonan-2-yl)amino]-5,5,5-trifluoro-4,4-dimethyl-pentoxy]-6-(2,6-dimethylphenyl)-5-methyl-pyrimidin-2-yl]sulfamoyl]benzoic acid

In a 20 mL vial, 3-[[4-chloro-6-(2,6-dimethylphenyl)-5-methyl-pyrimidin-2-yl]sulfamoyl]benzoic acid (430 mg, 0.9956 mmol) and tert-butyl 2-[[(1R)-4,4,4-trifluoro-1-(hydroxymethyl)-3,3-dimethyl-butyl]amino]-7-azaspiro[3.5]nonane-7-carboxylate (412 mg, 1.009 mmol) were charged under nitrogen with anhydrous THF (4 mL). Sodium tert-butoxide (493 mg, 5.130 mmol) was added (slight exotherm). The reaction was stirred at room temperature for 6 hours. The mixture was partitioned between ethyl acetate (50 mL) and aqueous 1M HCl (40 mL) and brine (20 mL). After separation, the aqueous phase was further extracted with EtOAc (2×30 mL).

To the resulting yellow oil, toluene was added (100 mL) and the white precipitate was washed with cold THF (300 mL) and cold Et₂O (300 mL). Removal of all the volatiles and drying in vacuo yielded cyclohexyl(triphenyl)phosphonium bromide (77.2 g, 67%) as a white powder. ¹H NMR (500 MHz, Chloroform-d) δ 8.00 (dd, J=11.9, 7.7 Hz, 5H), 7.78-7.64 (m, 8H), 7.59-7.41 (m, 2H), 5.38 (t, J=12.4 Hz, 1H), 2.15 (d, J=12.3 Hz, 4H), 1.85-1.67 (m, 3H), 1.10-0.94 (m, 3H).

Step 2: (2-Bromo-3-methyl-phenyl)methanol

To a solution of LiBH₄ in THF (95.0 mL of 2 M, 190.0 mmol) stirring under nitrogen atmosphere and cooled in an ice-water bath was slowly added a solution of methyl 2-bromo-3-methyl-benzoate (30 g, 130.96 mmol) in ether (200 mL). Upon completion of reagent addition, the mixture was warmed to room temperature and stirred for 16 h. The mixture was quenched by the slow addition of 0.5 N HCl (50 mL) until pH=6-7. The resulting mixture was extracted with diethyl ether and the organic layer was washed with brine, dried (sodium sulfate), filtered and concentrated to give (2-bromo-3-methyl-phenyl)methanol (25.68 g, 93%); ESI-MS m/z calc. 199.9837, found 183.5 (M+1-18)⁺; Retention time: 2.53 minutes; LC Method T.

Step 3: 2-Bromo-3-methyl-benzaldehyde

PhI(OAc)₂ (48 g, 149.02 mmol) was added to a solution of (2-bromo-3-methyl-phenyl)methanol (25.68 g, 121.34 mmol) and TEMPO (2.1 g, 13.440 mmol) in DCM (210 mL). The reaction mixture was stirred until the alcohol was no longer detectable (TLC), and then it was diluted with DCM. The mixture was washed with sat. Na₂S₂O₃ solution and extracted with DCM. The combined organic extracts were washed with aq. NaHCO₃, dried over anhydrous Na₂SO₄, and concentrated. The crude was purified by silica gel chromatography (80 g silica, 0-30% gradient of EtOAc in hexanes) to afford 2-bromo-3-methyl-benzaldehyde (22.1 g, 91%) as a white solid.

Step 4: 2-Bromo-1-(cyclohexylidenemethyl)-3-methyl-benzene

To a suspension of cyclohexyl(triphenyl)phosphonium;bromide (77.2 g, 181.50 mmol) in THF (220 mL) at 0° C. was added potassium tert-butoxide (26.165 g, 233.17 mmol) in THE (220 mL). The mixture was then stirred at RT for 1 h. The mixture was then cooled back down to 0° C. and a solution of 2-bromo-3-methyl-benzaldehyde (22.1 g, 111.03 mmol) in THE (45 mL) was added. The reaction was then stirred at RT for 17 h. The reaction mixture was then quenched with cold water (200 mL) and the aqueous layer was extracted with EtOAc (2×300 mL). The organic layers were then combined, washed with brine, dried with anhydrous Na₂SO₄, filtered, and concentrated under reduced pressure. The crude product was then purified via silica gel column chromatography (eluting with 0 to 5% EtOAc in hexanes) to yield 2-bromo-1-(cyclohexylidenemethyl)-3-methyl-benzene (24.66 g, 82%) as a clear oil. ¹H NMR (500 MHz, Chloroform-d) δ 7.17-7.06 (m, 2H), 7.03 (m, 1H), 6.19 (s, 1H), 2.43 (s, 3H), 2.33-2.25 (m, 2H), 2.24-2.16 (m, 2H), 1.72-1.64 (m, 2H), 1.64-1.58 (m, 2H), 1.55 (m, 2H).

Step 5: 2-[2-(Cyclohexylidenemethyl)-6-methyl-phenyl]-4,4,5,5-tetramethyl-1,3,2-dioxaborolane

In a 20-mL sealed tube was added 2-bromo-1-(cyclohexylidenemethyl)-3-methyl-benzene (34.9 g, 125.02 mmol) in dioxane (300 mL), and KOAc (29 g, 295.49 mmol) was added. The resulting mixture was degassed with N₂ for several minutes. Then, 4,4,5,5-tetramethyl-2-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-1,3,2-dioxaborolane (54 g, 212.65 mmol) was added, followed by Pd(dppf)Cl₂ (9 g, 12.3 mmol), and the reaction was purged again by N₂, sealed and heated at 100° C. for 16 h. Thereafter, the reaction was cooled to room temperature, saturated ammonium chloride solution was added, and the mixture was extracted with ethyl acetate. The combined organic extracts washed with brine, dried over sodium sulfate, filtered and concentrated. The resulting brown oil was purified utilizing silica gel chromatography (330 g×2 of silica, 0-15% gradient of EtOAc in hexanes) to afford 2-[2-(cyclohexylidenemethyl)-6-methyl-phenyl]-4,4,5,5-tetramethyl-1,3,2-dioxaborolane (24 g, 61%) as a yellow oil. ESI-MS m/z calc. 312.22607, found 313.4 (M+1)⁺; Retention time: 4.62 minutes; LC Method T.

Step 6: tert-Butyl N-tert-butoxycarbonyl-N-[4-chloro-6-[2-(cyclohexylidenemethyl)-6-methyl-phenyl]-5-methyl-pyrimidin-2-yl]carbamate

To a slurry of tert-butyl N-tert-butoxycarbonyl-N-(4,6-dichloro-5-methyl-pyrimidin-2-yl)carbamate (12.4 g, 31.143 mmol), 2-[2-(cyclohexylidenemethyl)-6-methyl-phenyl]-4,4,5,5-tetramethyl-1,3,2-dioxaborolane (12 g, 36.509 mmol) and Cs₂CO₃ (25 g, 76.730 mmol) in dimethoxyethane (100 mL) and H₂O (20 mL) was added Pd(dppf)Cl₂ (1.1 g, 1.5033 mmol), and the mixture was vigorously stirred under nitrogen at 80° C. (reflux) for 3 h. The reaction mixture was cooled to ambient temperature and diluted with water (100 mL). The aqueous phase was separated and extracted with EtOAc (100 mL).

VI. Bioactivity A. 3T3 Assay 1. Membrane Potential Optical Methods for Assaying F508del Modulation Properties of Compounds

The assay utilizes fluorescent voltage sensing dyes to measure changes in membrane potential using a fluorescent plate reader (e.g., FLIPR III, Molecular Devices, Inc.) as a readout for increase in functional F508del in NIH 3T3 cells. The driving force for the response is the creation of a chloride ion gradient in conjunction with channel activation by a single liquid addition step after the cells have previously been treated with compounds and subsequently loaded with a voltage sensing dye.

2. Identification of Corrector Compounds

To identify correctors of F508del, a single-addition HTS assay format was developed. This HTS assay utilizes fluorescent voltage sensing dyes to measure changes in membrane potential on the FLIPR III as a measurement for increase in gating (conductance) of F508del in F508del NIH 3T3 cells. The F508del NIH 3T3 cell cultures were incubated with the corrector compounds at a range of concentrations for 18-24 hours at 37° C., and subsequently loaded with a redistribution dye. The driving force for the response is a Cl⁻ ion gradient in conjunction with channel activation with forskolin in a single liquid addition step using a fluorescent plate reader such as FLIPR III. The efficacy and potency of the putative F508del correctors was compared to that of the known corrector, lumacaftor, in combination with acutely added 300 nM Ivacaftor.

A functional CFTR assay using primary cystic fibrosis intestinal organoids. Nat Med. 2013 July; 19(7):939-45.).

3. Enteroid Cell Harvesting and Seeding

Cells were recovered in cell recovery solution, collected by centrifugation at 650 rpm for 5 min at 4° C., resuspended in TryPLE and incubated for 5 min at 37° C. Cells were then collected by centrifugation at 650 rpm for 5 min at 4° C. and resuspended in IEMM containing 10 μM ROCK inhibitor (RI).

Cells were seeded at 5000 cells/well into multi-well plates and incubated for overnight at 37° C., 95% humidity and 5% CO₂ prior to assay.

4. Membrane Potential Dye, Enteroid Assay A

Enteroid cells were incubated with test compound in IEMM for 18-24 hours at 37° C., 95% humidity and 5% CO₂. Following compound incubations, a membrane potential dye assay was employed using a FLIPR Tetra to directly measure the potency and efficacy of the test compound on CFTR-mediated chloride transport following acute addition of 10 μM forskolin and 300 nM N-[2,4-bis(1,1-dimethylethyl)-5-hydroxyphenyl]-1,4-dihydro-4-oxoquinoline-3-carboxamide. Briefly, cells were washed 5 times in Bath 1 Buffer. Bath 1 Dye Solution was added, and the cells were incubated for 25 min at room temperature. Following dye incubation, cells were washed 3 times in Chloride Free Dye Solution. Chloride transport was initiated by addition of Chloride Free Dye Stimulation Solution and the fluorescence signal was read for 15 min. The CFTR-mediated chloride transport for each condition was determined from the AUC of the fluorescence response to acute forskolin and 300 nM N-[2,4-bis(1,1-dimethylethyl)-5-hydroxyphenyl]-1,4-dihydro-4-oxoquinoline-3-carboxamide stimulation. Chloride transport was then expressed as a percentage of the chloride transport following treatment with 3 μM (S)—N-((6-aminopyridin-2-yl)sulfonyl)-6-(3-fluoro-5-isobutoxyphenyl)-2-(2,2,4-trimethylpyrrolidin-1-yl)nicotinamide, 3 μM (R)-1-(2,2-difluorobenzo[d][1,3]dioxol-5-yl)-N-(1-(2,3-dihydroxypropyl)-6-fluoro-2-(1-hydroxy-2-methylpropan-2-yl)-1H-indol-5-yl)cyclopropanecarboxamide and 300 nM acute N-[2,4-bis(1,1-dimethylethyl)-5-hydroxyphenyl]-1,4-dihydro-4-oxoquinoline-3-carboxamide triple combination control (% Activity).

Chloride transport was then expressed as a percentage of the chloride transport following treatment with 1 μM (14S)-8-[3-(2-{Dispiro[2.0.2.1]heptan-7-yl}ethoxy)-1H-pyrazol-1-yl]-12,12-dimethyl-2λ⁶-thia-3,9,11,18,23-pentaazatetracyclo[17.3.1.111,14.05,10]tetracosa-1(22),5,7,9,19(23),20-hexaene-2,2,4-trione, 3 μM (R)-1-(2,2-difluorobenzo[d][1,3]dioxol-5-yl)-N-(1-(2,3-dihydroxypropyl)-6-fluoro-2-(1-hydroxy-2-methylpropan-2-yl)-1H-indol-5-yl)cyclopropanecarboxamide and 300 nM acute N-[2,4-bis(1,1-dimethylethyl)-5-hydroxyphenyl]-1,4-dihydro-4-oxoquinoline-3-carboxamide triple combination control (% Activity).

C. HBE Assay 1. Ussing Chamber Assay of CFTR-Mediated Short-Circuit Currents

Ussing chamber experiments were performed using human bronchial epithelial (HBE) cells derived from CF subjects heterozygous for F508del and a minimal function CFTR mutation (F508del/MF-HBE) and cultured as previously described (Neuberger T, Burton B, Clark H, Van Goor F Methods Mol Biol 2011:741:39-54). After four days the apical media was removed, and the cells were grown at an air liquid interface for >14 days prior to use. This resulted in a monolayer of fully differentiated columnar cells that were ciliated, features that are characteristic of human bronchial airway epithelia.

To isolate the CFTR-mediated short-circuit (I_(SC)) current, F508del/MF-HBE grown on Costar® Snapwell™ cell culture inserts were mounted in an Ussing chamber and the transepithelial I_(SC) was measured under voltage-clamp recording conditions (V_(hold)=0 mV) at 37° C. The basolateral solution contained (in mM) 145 NaCl, 0.83 K₂HIPO₄, 3.3 KH₂PO₄, 1.2 MgCl₂, 1.2 CaCl₂), 10 Glucose, 10 HEPES (pH adjusted to 7.4 with NaOH) and the apical solution contained (in mM) 145 NaGluconate, 1.2 MgCl₂, 1.2 CaCl₂), 10 glucose, 10 HEPES (pH adjusted to 7.4 with NaOH) and 30 μM amiloride to block the epithelial sodium channel. Forskolin (20 μM) was added to the apical surface to activate CFTR, followed by apical addition of a CFTR inhibitor cocktail consisting of BPO, GlyH-101, and CFTR inhibitor 172 (each at 20 μM final assay concentration) to specifically isolate CFTR currents. The CFTR-mediated I_(SC) (μA/cm²) for each condition was determined from the peak forskolin response to the steady-state current following inhibition.

2. Identification of Corrector Compounds

The activity of the CFTR corrector compounds on the CFTR-mediated I_(SC) was determined in Ussing chamber studies as described above. The F508del/MF-HBE cell cultures were either incubated with the corrector compounds at a range of concentrations in combination with 1 μM Ivacaftor or were incubated with the corrector compounds at a single fixed concentration of 10 μM in combination with 1 μM Ivacaftor for 18-24 hours at 37° C. and in the presence of 20% human serum. The concentration of corrector compounds with 1 μM Ivacaftor during the 18-24 hours incubations was kept constant throughout the Ussing chamber measurement of the CFTR-mediated I_(SC) to ensure compounds were present throughout the entire experiment. The efficacy and potency of the putative F508del correctors was compared to that of the known Vertex corrector, (14S)-8-[3-(2-{Dispiro[2.0.2.1]heptan-7-yl}ethoxy)-1H-pyrazol-1-yl]-12,12-dimethyl-2λ⁶-thia-3,9,11,18,23-pentaazatetracyclo[17.3.1.111,14.05,10]tetracosa-1(22),5,7,9,19(23),20-hexaene-2,2,4-trione, in combination with 18 μM Tezacaftor and 1 μM Ivacaftor.

D. Biological Activity 1. Assay Procedures (a) HBE Assay (1) Ussing Chamber Assay of CFTR-Mediated Short-Circuit Currents

Ussing chamber experiments were performed using human bronchial epithelial (HBE) cells derived from CF subjects heterozygous for F508del and a minimal function CFTR mutation (F508del/MF-HBE) and cultured as previously described (Neuberger T, Burton B, Clark H, Van Goor F Methods Mol Biol 2011:741:39-54). After four days the apical media was removed, and the cells were grown at an air liquid interface for >14 days prior to use. This resulted in a monolayer of fully differentiated columnar cells that were ciliated, features that are characteristic of human bronchial airway epithelia.

To isolate the CFTR-mediated short-circuit (I_(SC)) current, F508del/MF-HBE grown on Costar® Snapwell™ cell culture inserts were mounted in an Ussing chamber and the transepithelial I_(SC) was measured under voltage-clamp recording conditions (V_(hold)=0 mV) at 37° C. The basolateral solution contained (in mM) 145 NaCl, 0.83 K₂HPO₄, 3.3 KH₂PO₄, 1.2 MgCl₂, 1.2 CaCl₂), 10 Glucose, 10 HEPES (pH adjusted to 7.4 with NaOH) and the apical solution contained (in mM) 145 NaGluconate, 1.2 MgCl₂, 1.2 CaCl₂), 10 glucose, 10 HEPES (pH adjusted to 7.4 with NaOH) and 30 μM amiloride to block the epithelial sodium channel. Forskolin (20 μM) was added to the apical surface to activate CFTR, followed by apical addition of a CFTR inhibitor cocktail consisting of BPO, GlyH-101, and CFTR inhibitor 172 (each at 20 μM final assay concentration) to specifically isolate CFTR currents. The CFTR-mediated I_(SC) (μA/cm²) for each condition was determined from the peak forskolin response to the steady-state current following inhibition.

(2) Identification of Corrector Compounds

The activity of the CFTR corrector compounds on the CFTR-mediated I_(SC) was determined in Ussing chamber studies as described above. The F508del/MF-HBE cell cultures were either incubated with the corrector compounds at a range of concentrations in combination with 1 μM Ivacaftor or were incubated with the corrector compounds at a single fixed concentration of 10 μM in combination with 1 μM Ivacaftor for 18-24 hours at 37° C. and in the presence of 20% human serum. The concentration of corrector compounds with 1 μM Ivacaftor during the 18-24 hours incubations was kept constant throughout the Ussing chamber measurement of the CFTR-mediated I_(SC) to ensure compounds were present throughout the entire experiment. The efficacy and potency of the putative F508del correctors was compared to that of the known Vertex corrector, (14S)-8-[3-(2-{Dispiro[2.0.2.1]heptan-7-yl}ethoxy)-1H-pyrazol-1-yl]-12,12-dimethyl-2λ⁶-thia-3,9,11,18,23-pentaazatetracyclo[17.3.1.111,14.05,10]tetracosa-1(22),5,7,9,19(23),20-hexaene-2,2,4-trione, in combination with 18 μM Tezacaftor and 1 μM Ivacaftor.

Reagents and starting materials were obtained by commercial sources unless otherwise stated and were used without purification.

Proton and carbon NMR spectra were acquired on either a Bruker Biospin DRX 400 MHz FTNMR spectrometer operating at a ¹H and ¹³C resonant frequency of 400 and 100 MHz respectively, or on a 300 MHz NMR spectrometer. One dimensional proton and carbon spectra were acquired using a broadband observe (BBFO) probe with 20 Hz sample rotation at 0.1834 and 0.9083 Hz/Pt digital resolution respectively. All proton and carbon spectra were acquired with temperature control at 30° C. using standard, previously published pulse sequences and routine processing parameters.

NMR (1D & 2D) spectra were also recorded on a Bruker AVNEO 400 MHz spectrometer operating at 400 MHz and 100 MHz respectively equipped with a 5 mm multinuclear Iprobe.

NMR spectra were also recorded on a Varian Mercury NMR instrument at 300 MHz for ¹H using a 45 degree pulse angle, a spectral width of 4800 Hz and 28860 points of acquisition. FID were zero-filled to 32k points and a line broadening of 0.3 Hz was applied before Fourier transform. ¹⁹F NMR spectra were recorded at 282 MHz using a 30 degree pulse angle, a spectral width of 100 kHz and 59202 points were acquired.
